如何在詹金斯管道中仅获取当前阶段的控制台输出？

Question

我试图在jenkins管道中仅获取当前阶段的控制台输出。我的最终目标是存储此输出，直到构建发布步骤为止，然后通过不和谐通知发出该输出。

        stage("Build Javadoc") {
            steps { 
                script {
                    try {
                        sh script: "cd ${params.PLUGIN} && /opt/gradle/bin/gradle atherysdoc"
                    } catch (Exception e) {
                        exception = e;
                        failureReason = // Get current stage console output?
                        throw e;
                    }
                } 
            }
        }

        failure {
            discordSend webhookURL: "https://discordapp.com/api/webhooks/blahblah",
                        title: "Build Failure: ${fullPluginName}",
                        successful: false,
                        result: 'FAILURE',
                        link: env.BUILD_URL,
                        description: "${exception}\n```${failureReason}```"
        }

我想要这样做的原因是因为仅发出失败的shell命令异常是因为结果为hudson.AbortException: script returned exit code 1，这不是很有帮助
